Thank you for the comments and additional examples, particularly on the Grimm article. No wonder I was never able to get a handle on this expression!

I suppose we have yet to see whether the meaning of this expression will morph into two clear and distinct meanings or remain one meaning and one muddled use.

No longer really relevant but FWIW, the China article at uses the expression at the end, but I should have pointed out the word "game" is left out:

"We hope the US will abandon its zero-sum thought and play a constructive role in increasing mutual trust, promoting common development and maintaining regional peace and stability."
